What is an aquifer?
a layer underground that stores water for human use (crops and livestock)
What are tributaries?

What is surface tension?
The tightness across an area of water, usually allows for certain things to stay on top of water

What is Eutrophication and provide an example
The process by which an abundance of nutrients is released into a pond and there is not enough plants, animals to take in all these nutrients and the body of water begins to dry up.
A farm pond slowly drying up over the course of ten years.

What is capillary action?

Bogs- found more north, peaty substance on top of water
Swamps- found in more warmer environments, very humid, tall trees grow throughout, Southern US
What is transpiration?
The process by which the water in leaves and trees is evaporated
What is the difference between permeable materials and impermeable materials?
Permeable allows water to flow through it (sand,gravel) while impermeable does not allow (bedrock, clay)
What two places on Earth do we find the majority of the freshwater?
Frozen Ice and Under Ground
Why does water have such high specific heat?
Because of the attraction among water molecules
What do wetlands do?
natural water filter, habitat for organisms, helps prevent floods
What is infiltration?
When water goes into the ground and is absorbed by all the surrounding vegetation and plants
How does water underground come to the surface?
Springs and Geysers
